Yamaha YZ450F

With its ultra-compact layout, outstanding power and agile cornering, the YZ450F delivers the technology and performance needed to take you to the victorYZone, making this bike the clear choice for every racer who wants to discover their true winning potential.

Its reversed head engine and rearward-slanted cylinder deliver optimum intake efficiency for phenomenal performance – and for 2022 the YZ450F comes with class-leading suspension featuring revised low speed damping settings for even better handling, as well as a lighter rear hub and new chain that reduce unsprung weight.

Finished in Team Yamaha Blue duo-tone colours with new in-mould graphics, the YZ450F is ready to tune in to victory.

Features

Ultra-compact high-tech 450cc engine

Ultra-compact high-tech 450cc engine

The YZ450F’s 450cc reversed head engine is a proven MXGP race winner that has the performance to take the top step of the podium against the world’s best. The front facing inlet ensures optimum intake efficiency, and its compact dimensions help to centralise mass for sharper handling.

Lightweight aluminium beam frame

Lightweight aluminium beam frame

In order to achieve the best balance of chassis strength and rigidity, the YZ450F’s bilateral beam frame uses varying thicknesses of aluminium throughout its structure. The desired rigidity balance is also achieved by using a special combination of steel and aluminium engine mounts, for agile handling and precise cornering.

Easy-to-use Power Tuner app

Easy-to-use Power Tuner app

YZ450F riders can benefit from a smart piece of software that can give you a real advantage. Using your smartphone it’s simple to tune the engine’s power delivery with the Yamaha Power Tuner app. The easy-to-use system enables you to outperform the opposition in varying track and surface conditions.

Handlebar-mounted 2-mode mapping switch

Handlebar-mounted 2-mode mapping switch

Once you’ve selected your two preferred engine maps and preloaded them for your riding session using the Power Tuner app you can select your mapping using the handlebar-mounted switch. This on-the-fly adjustment enables you to switch the mapping mode – with the throttle shut – while riding, giving you the ultimate control in all conditions.

Improved suspension settings

Improved suspension settings

Yamaha’s suspension is one of the best standard set-ups fitted to a production bike, and for 2022 the best-in-class SSS (Speed Sensitive System) front forks and the tried and tested monocross rear suspension feature revised low speed damping settings – for better handling and excellent feedback.

Launch Control System

Launch Control System

The YZ450F’s Launch Control System (LCS) optimises the engine’s power output and running characteristics during the first few seconds of the race after the gate drops. By helping to transmit power more efficiently, the LCS gives you greater controllability off the starting line, increasing your holeshot-winning performance every time.

New lightweight chassis components

New lightweight chassis components

Any reduction to unsprung weight makes a significant improvement in suspension performance, and the 2022 YZ450F is fitted with a new lightweight rear hub as well as a lighter chain that shave 0.2kg off the weight.

Mass-centralised wraparound exhaust

Mass-centralised wraparound exhaust

For enhanced mass-centralisation the YZ450F is fitted with a wraparound exhaust that snakes around the cylinder, and this design enables the fitment of a muffler that is mounted further forwards. Combined with the rearward-slanted cylinder, this design helps to keep weight close to the bike’s centre for light and agile nimble handling.

Robust clutch and transmission

Robust clutch and transmission

The robust 5-speed transmission benefits from specially-developed gears with a large surface area – and together with a heavy-duty clutch this delivers high levels of durability. And for a positive feel when shifting gear, the shift drum and selectors are designed to give a short stroke.

New graphics and duo-tone body colours

New graphics and duo-tone body colours

The latest generation Yamaha motocross bikes come with dynamic Yamaha Blue duo-tone body colours and new in-mould graphics, that are designed to resist wear and tear and keep looking good after many motos.
